This word suggests that the creatures might have a fiery appearance or resemble snakes. Because we do not know exactly what "seraphim" means, you could translate these as "creatures" or "living things" or "beings." Or you can borrow the word and use it in your language. See how you translated this word in [Isaiah 6:2](./01.md). (See: [[rc://en/ta/man/translate/translate-unknown]] and [[rc://en/ta/man/translate/translate-transliterate]])
These two phrases say basically the same thing. This can be stated in active form. AT: "Yahweh has taken away your guilt and has forgiven your sins" (See: [[rc://en/ta/man/translate/figs-parallelism]] and [[rc://en/ta/man/translate/figs-activepassive]])
Yahweh no longer considering a person to be guilty is spoken of as if "guilt" were an object that someone could take away from someone else. (See: [[rc://en/ta/man/translate/figs-metaphor]])
